Hi Tibi and any other builders,
So I can use my motor cable and a bench DC power supply and all motor functions work so...pin 1-2 to the spindle from pcb and pin 5-6 stop[return] function from pcb are not functioning. Pin 3-4 gear drive is functioning. I have datasheets for 3 main IC's but I'm not really sure where to start troubleshooting, any suggestions would be greatly appreciated. Thanks!
regards,
Steve

Hi Tibi,
So I was just reading 2012 SHIGA CD manual as posted in google docs. I have not removed any ferrite beads for separate power to V1-4. I am not sure exactly which have to go as I have V1/V3 on separate and V2/V4 on miniregs. It seemed to be saying if V3 is separate all others have to be also. V1 no L2, V2 no L3, V3 no L5, V4 no L4/L5. Can you confirm if I can do this and which ferrites go. Thanks
best regards,
Steve

Hi Tibi,
Well no miracle yet but I think trashed my motor cable and I am waiting for some new connectors to arrive. I had a 2 pin connector to play with and I can drive laser motor with 3-4 but will only stop when CD door button is pressed and held. When released it over drives away from disc spindle and won't stop. Still no spindle spin 1-2 pins out. If I use pins 3-4 out to 1-2 at motor spindle spins. If worse case scenario will board tolerate hot air rework to remove damaged IC's? Thanks again for help

Need some help!
Hi all, some time ago I recived my Shiga and now I have had time to set everything up on a temporary board to test it and let it burn in but I have some problem occuring here.
I took an transformer I had in house, 12-0-12 volt 1.5 Amp so it should do even if the regulator will run a little hot but with a bigger sink it should be ok.
Connected the PSU and I had stable 8.01 volt without connecting to main board so I did continue the connection.
Started up the Shiga and the motors are running but I get no TOC reading.
It start running in five sequenses with stop about a second in between and and then come up with dubble zero in the LCD. I have gone through the thread here about 3 times to get some idea, so I have checked the motor cable and connections and there is nothing wrong.
Checked all cables for any dents and nicks but they are ok.
When I connected the main board I have stable 7.99 volts from the PSU and I get the same reading when checking the pad feeding the V1-V4 regulators so I have full voltage to the main board.
I have checked the laser and there is something fishy cause the laser head should be moving up/down but it is dead. The sled is moving to position trying to search but the laser head doesn't move to focus. I checked the laser with my phone and I can not see any laser light and I have tested before on other Players so I know that the camera would catch any laser light but here it is dead.
The motor cable (J2) is giving pin 2, 4.960 V and pin 3,4 give 3.480 V and pin 5, 6 give 3.591 V and at the motor board I have about the same readings.
I really don't know where to go from here but I want it running cause it is not funny to start modding without knowing what it sound like before changing anything.
Anyone who have an idea what to do next?
